About the event

We are delighted to be back on the Sunday 6th August 2023 for the Cowman, Calfman and Stampede Triathlon and Aquabike events at the stunning venue of Emberton Country Park.

The Cowman is a middle distance triathlon (1.9km swim, 90km bike, 21.1km run). The Calfman is half of a middle distance (900m swim, 45km bike, 10km run) and the Stampede (introduced in 2018) is a sprint distance (750m swim, 22k bike, 5.25k run).

The swim takes place in the lake adjacent to the sailing club, with the bike course heading out around the local area (2 laps for Cowman, 1 lap for Calfman, short lap for the Stampede), and the run course circulating the lake featuring both on- and off-road sections (4 laps for Cowman, 2 laps for Calfman, 1 lap for the Stampede). Aquabike athletes will start with the their respective Triathlon distance athletes and will follow the same swim and bike course.

This event will be taking place with a mass start unless otherwise stated due to the COVID-19 measures at the time.

All athletes will receive a bespoke eco-friendly wooden medal with the option of purchasing a T-shirt and/or a Hoodie too!

There will be trophies for the 1st, 2nd and 3rd male and female in each distance and 1st male and female in the following age categories:

  • Vet40
  • Vet50
  • Vet60
